Week 1 - I turned my focus to the testing of the active collimator. I read sections of “Quality Assurance and Acceptance Test Plan for the Tagger Microscope and Active Collimator.” There are numerous references to other documents that would help me (D0000-19-02-S003 - Specification of the active collimator and electronics), but I was unable to find them on the GlueX wiki page. I have asked Alex and Dr. Jones to acquire the file for me.
Alex looked over the write up for the piping project. I fixed various pieces according to his suggestions. I then continued reading about the active collimator. Ann Marie picked up the Tektronix TDS 2024 oscilloscope from downstairs for me. I spent some time familiarizing myself with it, as I have never worked with this particular oscilloscope before. I downloaded the pdf and spent time learning how to use it. I also started reading “A Tungsten Pin Cushion Photon Beam Monitor” to further understand the relationship between the knock-on electrons in the showering medium and the differences in the currents through the collimator that are used to pinpoint the location of the photon beam.
Week 2 - I attempted to test the tungsten pin cushions within the active collimator. I connected one of the pin cushions to a PMT-5R transimpedance amplifier, which was then connected to the oscilloscope. Dr. Jones told me to also use a F-100PS power supply. I attempted to connect the power supply to the amplifier via a F3B207-06 DB9 Belkin serial cable. However, this seemed to have made the power supply short out. I am awaiting Dr. Jones’ instructions for what to do about this matter; Neither Jim nor Ann Marie are able to help me with this problem.
I looked into buying a new F-100ps power supply. Dr. Jones and I removed the fuse from the power supply, and found that it needed replacement. I went to Mansfield Supply, and ordered a set of new fuses to place in the power supply.
Week 3 - The fuses came in. I had time to quickly test that the power supply was still functional. I replaced the fuse, and the power supply's "Power" light turned on.
